Several months after Christina Grimmie was tragically shot and killed at a meet and greet after her show in Florida, celebrities are still paying tribute to the star.

Christina was widely recognized for her run on NBC's hit series The Voice as she worked with Adam Levine as her coach throughout her journey. During that time, these two got very close. With her powerful vocals and vibrant personality, Christina left an impression on the rest of the judges as well.

The first episode of the new season of The Voice premiered on Sunday night and all four coaches, Adam, Blake Shelton, Miley Cyrus and Alicia Keys, paid tribute to Christina. They put their voices together belting out an amazing rendition of "Dream On" by Aerosmith.

At the end of their performance, the screen went black and the words, "In loving memory of our friend Christina Grimmie," showed up.

Hearing all four of their voices together and the presence they had on stage was insanely powerful. It was not only something for the crowd to enjoy but something Christina would have loved as well. Just by watching the video, fans can see and even feel the harmony, energy and spirit that was so profoundly evident on stage.
